I don’t think the first element has defined behavior unless it is
ingested by an XSLT processor (or unless you’ve read some documentation
about what elements in the xsl: namespace “mean”).
Equally, I could write some software that took the “airport” element and
performed operations as a result. And without knowing what namespace
airport is in, or what documentation you might have at hand which
describes the semantics of elements in that namespace, it’s impossible
to say.

Maybe. I don’t think it’s useful in a precise, technical sense, but it’s
often a shortcut in describing vocabularies informally.
Be seeing you,
